In the embodiment illustrated, a cabinet 1 1s provided hav ng the end oftub 2 received therein and wringer 3 detachably secured and mounted fordownwardmovement in a manner that -w1ll be presently described.

The invention, however, is not limited to the speclfic cabinet and tubbut is applicableto Y cabinets and tubsof various types.

On a braced in thecabinet 1, a bracket 5 is mounted, (Fig. 5); havlng alug 6 thereon,

and constituting afsupport for a plate 7 secured thereto by a hinge .8,'l The plate 7" hasua notch 10, therein: adaptedto; permit hingedmovement of the plate v7 past the lug 6. I The plate 7( also has a lugllthereon andis rigid with. asleevelQ; IA lower drive shaft section;1-3 isrotatably mounted in the 1 bracket and isrigid; with a clutch member I14 (F l g 3) adaptedto cooperateqwitli a gravity-actuated clutch memben15 keycd. for sl ding movement .on an vupper; shaft section 16 in thesleeve 12 A projection 17 on the sleeve 12, received in an annularrecess 18in the clutch member 15, limits its sliding 'movement andretains it inthesleevelQ. A

tubular: support 20 fora wringer frame 21 surrounds the sleeve 12andhasaflange 22 thereonadjacent to the plate 7. I The flange 22 has anotch 23 therein, adapted,=in different positions of the wringcr 3, topermit, movementaofthe fiange22 pastithe lugsfi and 11, as willpresently be described A manually controllable latch 24;, urged hy-a j.

spring 25, ispivoted on the support 20-and extends, at one end, throughan opening :26. tl1818l11,lflt0 one of four recesses 27 in the sleeve12. y l v The wringer per shaft section 16 as an axis and may be retained in any one of four vertical positions 909 apart by the latch -24cooperating "selec- 3 may be swung about the np-y tively with one of theIrecesses'27; One of the positions is shown in Fig. 1 wherein thewringer 3 is illustrated as parallel to the plane of the adjacent sideof the cabinet. Fig. 9 illustrates thisposition of the wringerdiagrammatically without a showing of the cabinet.

\Vhen the wringer 3 is in any of the four principal positions, it cannot be moved upwardly, since the notch 23 is spac'cd laterally away fromthe lug 11. and the lug 11 will prevent upward n'iovement of the flange22, as is apparent from Figs. 7 and 9.

If it is desired to fold the wringer downwardly, the tub 2 is removed,in a manner described in the aforementioned application, Serial No.707,801, and the wringer is swung: about a vertical axis to bring thenotch J3 immediately below the lug 11. and in registry with the notch10. This position is shown in Fig. 10. It may then he moved about thehinge S, to the position shown in Fig. 11, the notches 10 and 23permitting: the flanges 7 and 22 to pass the lug 6. Fig. 6 shows theposition of parts after the. flange 22 has passed the lug 6 and thewringer has again been slightly turned about the shaft section 16 as anaxis. The wringer may be lowered to a completely inverted position,

as shown in full lines in Fig. 2 which illustrates a collapsed positionof washingmachine parts disclosed in the aforementioned application,Serial No. 707.801 the specific features of which are not essential tothis invention. Fig. 1 1 shows this position of the wringerdiagrammatically.

If, instead of folding, it is desired to remove the wringer, it is movedon the hinge 8 until the flange 7 is higher than the lug 6. (Fig. 11)then the wringer 3 is rotated about the upper shaft section 16 as anaxis until the notch 23 is beneath the lug 11, (Fi pll). It may then bedrawn upwardly, the tubular support sliding on the sleeve 12 until it isentirely removed (Fig. 13).

A reverse movement of the wringer 3 will restore it to locked relationwith respect to the plate 7 and the sleeve 12. To return it toup-rigrht. position, it is then rotated until the notches 23 and 10 arein registry, whereupon it is moved upwardly about the hinge 8. Rotationof the wringer about the upper shaft section 16 as an axis will thencause the flange 22 to move under the lug 6 and lock the wrin aer inplace.

On the movement of the wringer 3 into elevated position, the upperclutch member 15 is permitted to slide downwardly and to engage with thelower clutch mel'nber 1 1, thus coupling the shaft sections 13 and 16 indriving relation.

The wringer 3 is provided with a roll-release mechanism.

The upper shaft section 16 is connected. by a manually-controlledroll-reverse mechanism 28 of conventional construction, to the shaft 30of a roll 31. A gear 32 on the shaft 30 meshes with a gear 33 on theshaft 3*]: of an upper roll 35. The shaft 34: is journaled in hearingblocks 3 A bar 37 extends longitudinally of the wringer 3 and rests uponthe upper surfaces of the hearing blocks 36 for transmitting pressure tothe rolls, and a strap 136 extends from the bottom of one of the bearingblocks 36 upwardly and longitudinally of the wringer 3 above the bar 37,to which it is secured at points 40, and again dowmvardly, terminatingbelow the other bearing hloclt 36. i

A pair of lugs 41 are outwardly directed from the frame 21 and areengaged by a pair of plates 42 which are connected by a web 13 and by aroller +1 positioned between the. strap 38 and the bar 37. A spring 45engagus, at one end, the strap 39 and surronmls a rod 16 extendingtherefrom to the web -13 against which the other end of the spring -15abuts. A nut 47 on the rod 46 engages the other face of the web .3. Theroller 44 is adapted to rest against a cam +18 which also cooperateswith a'similar roller 50 and parts on the other end of the wringersimilar to those descril'ied. The cam 48 is rigid with a spindle 51journaled in an opening in the strap 38 and secured to a control bar 52.

\Vhen the parts are in wi'in zin position, as shown in Fig. 3, the forceof the spring 4+) tends to swing. the web 4-3 and the plates 12 aboutthe roller 44 as an axis but the engagement of the plates 42 with thelugs 11 causes the force of the spring to be directed downwardly forexerting pressure on the rolls 31 and To release the rolls, the operatorstrikes the control bar 52, thus rotating the cam 48 and permitting theroller 44 to move to wards the spindle 51. This removes the downwardurge of the spring 45 upon the bar 37. withdraws the ends of the plates42 from the lugs 41, as illustrated by dot-anddash lines in Fig. 1., andpermits substantially instantaneous upw: rd movement of the roll and thebearing blocks 36 in the frame 21. If desired, the upper roll and theentire release mechanism may he lifted 'out of the top of the wringerframe 21.

This facilitates cleaning of parts.

lVhen the cam 48 is in the release position, the ends of the plates 42may he positioned below the lugs 41. To reset the mechanism after itsrelease. the operator imparts rotative movement to the control bar 52and causes the cam 48 to move the rollers 44 and 50 outwardly. Thisbrings the ends of the plates 42 upwardly against the lugs 11 and putsthe spring and the rolls 36 and 31 under compression. The restoration ofthe rolls to the original pressure is thus accomplished without tensionadjustment.

The position of the spring 45 is such that very little room is taken upabove the rolls.

By providing a drive shaft in two alignable, relativelymovable sections,a need for special hinging or pivot mechanism in the neighborhood of thereversing mechanism is obviated. This featnre, together with the compactarranging of the spring 45 and associated parts, results in aconservation of space, as the Wringer' requires vcrylittle room in thecabinet.

The invention is not limited to the specific details of construction andoperation of the,

embodiment illustrated which may be extensively modified and varied. Forinstance,
